The 3-phase output is not an optimal output, and its output isn't the healthiest for a motor, especially for a heavy-duty motor like a siren.

Is it possible to at least make 220v 3 phase?

That way I can at least just get a phase converter like posted?

I'm not positive, but I think a motor shop could help you in doing that, but it'll cost you.

It is physically impossible to rewire a motor into a single phase version.

Skipping class for a mere video is a bad idea, period.

That would be a radio data stream.

They were discontinued decades ago.

It's a Whelen omnidirectional siren.

Wow, glad to see you weren't hurt, and good work helping out after the crash.

That said, I think mechanical sirens are definitely a better choice than electronic sirens. Not sure if it's a good example, but wasn't the Federal Q siren banned off fire trucks somewhere?

So you mean they just toss them to the ground or something?

But, really, they could make a few bucks by either selling them on the spot or auctioning them off to enthusiasts or smaller towns and the like.

Nope. Salt spots irreversibly damaged my aluminum siren speaker.
